Reactive on walks? Hides at the vet? Most of those behaviors aren't personality — they're under-socialization. Here's the plan.
Not every dog walks into a busy park wagging their tail. Some hide behind your legs. Some bark at every passerby. Some freeze. Some lunge. Many pup parents assume "that's just who they are." Here's the truth: a lot of those behaviors aren't personality — they're under-socialization. The very good news is that socialization isn't a one-time puppy class. It's an ongoing skill you can build at any age.
Often mistaken for "aggression," reactive behavior on leash is usually rooted in fear, frustration, or lack of exposure. The leash adds tension, the dog can't flee, and the barking is the overflow.
